‘It could knock a whole street down’: the art of defusing a second world war bomb

On 14 January this year, army and navy squads faced an unprecedented challenge: one bomb on a Plymouth building site, another floating on a dredger in Exmouth. That afternoon, the clock started ticking

Everyone at Exmouth Marina knew there was an unexploded German bomb in the water. Old hands at the dock had been saying so since the end of the second world war. But the marina had been dredged and re-dredged and nothing had ever come up. It had started to sound like an old wives’ tale. The marina is a busy stretch of water: a commercial port until the late 1990s that had since been converted into a home to private yachts. A bomb, you’d think, would have a hard time staying hidden. But in the middle of the afternoon on Wednesday 14 January 2026, 81 years after the end of the second world war, Steve Hockings-Thompson, the manager of Exmouth Marina, got a call from the crew of a dredging vessel telling him he’d better come out to the boat. “I thought: ‘Oh crikey. We’ve got a bit of an issue here,’” Hockings-Thompson told me recently.

He went out to the dredger, a squat barge that hauls silt and other debris from the marina floor on to a flat deck that resembles a steel sieve. Sitting on the deck was a huge hunk of metal, caked in mud and stones. As Hockings-Thompson got closer and saw its distinctive conical shape, he knew it was a bomb – a big one. The dredger was loaded with 20,000 litres of diesel fuel, so if the bomb detonated, it would be disastrous. He called the police, who quickly came to the scene. “And then,” he said, “all hell broke loose.”
